Abstract

Copper-ion conducting solid-polymer electrolyte systems based on Polyvinyl alcohol (PVA) has been prepared by solution cast technique. UV-VIS data show a broad peak in the wavelength region 600–800 nm due to complex formation. The 30 wt.% Cu(NO3)2 doped system has a maximum conductivity of 1.6×10−5 Scm−1 at room temperature. The conductance spectrum shows two distinct regions: a dc plateau and a dispersive region. The dielectric spectra show an increase in the dielectric constant with decreasing frequency. The transference number measurements reveal that the transport in these electrolytes is mainly due to ions.
